Also, Imidacloprid treatment led to a significant rise of hepatic malondialdehyde (MDA), tumor necrosis factor-alpha (TNF-α) and nitric oxide (N.O). On the other-hand, plasma total protein (TP) and albumin tended to a significant decrease due to IM treatment. Hepatic catalase, reduced glutathione (GSH) and superoxide dismutase (SOD) of IM group exhibited a significant decrease.</em><em> The histological study showed lesions in the liver of treated rats with IM.</em><em> Both </em><em>beta carotene and hesperidin mitigate the deleterious effects of IM on previous parameters as manifested by a significant decrease of MDA, N.O, liver enzymes, </em><em>and improved antioxidant enzyme levels and liver histology. The protective effect of</em><em> beta carotene and hesperidin</em><em> in combination is more pronounced.</em><em> Therefore, our results clarify the synergistic effect of these two antioxidants on alleviating imidacloprid toxicity.</em>https://absb.journals.ekb.eg/article_8164_33bdee1c30ab3719ccdd706082e0700a.pdfAl-Azhar University, Faculty of Science (Boys)Al-Azhar Bulletin of Science1110-253528Issue 1-C20170601ECOLOGICAL STUDY ON WATER AND SEDIMENTS IN A SECTION OF THE RIVER NILE, ASWAN, EGYPT AS INDICATION FOR WATER QUALITY WITH THE EXISTENCE OF THE TOURISTS SHIPS FLOATING.2944816510.21608/absb.2017.8165ENH.

According to law 48 (1982) for the protection of the River Nile and its tributaries from pollution, it is believed that there are a pollution of Nile water in three chosen sites may be due to many reasons discussed in details in this study.https://absb.journals.ekb.eg/article_8165_7737ace821637a473a5e996d627c67be.pdfAl-Azhar University, Faculty of Science (Boys)Al-Azhar Bulletin of Science1110-253528Issue 1-C20170601TAXONOMIC STUDIES ON TWO TEPHRITID SPECIES (ORDER: DIPTERA), BACTROCERA OLEAE AND B. ZONATA, USING THE CUTICULAR HYDROCARBONS PROFILE4554816610.21608/absb.2017.8166ENAhmad M.GalhoumDepartment of Zoology, Faculty of Science, Al–Azhar University, Cairo, EgyptJournal Article20170125The outer surface of insects (cuticle) is sheltered by a complex mixture of cuticular hydrocarbons (CHCs) play an important role in avoiding desiccation and defend the insects against diseases infestation. Identification and chemical analyses of insect cuticular hydrocarbons are vital practice toward insect control. The obtained results indicated the two studied species obviously differ in CHCs components (35 and 29 components characterized <em>B. oleae</em> and <em>B. zonata</em> respectively) and shared twelve components. All these components can be used (quantitatively and qualitatively) to identify and taxonomically separate them.The objective of this paper is to evaluate the using of cuticular hydrocarbons as taxonomic tools in two dipteran species, <em>Bactrocera oleae</em> and <em>B. zonata</em>.https://absb.journals.ekb.eg/article_8166_ed59fbb0bacc3ac476158bc97800cbce.pdf
